Steps to reproduce the problem:
1. Enable #shelf-new-ui & Restart
2. Disable Flag & restart
3. Go to Flags, will still be enabled(2+ times disables it)
*after first disable shelf behavior may or may not disable regardless of status in Flags menu

What is the expected behavior?
Flag should disable after 1st time

What went wrong?
Flag seems to be stuck in enable even after several tries

Did this work before? N/A
